We probably need to find out what the PnP device ID is if it doesn't get
found under pcm0/sbc0.

How about 'device pcm0' and 'device sbc0'?

The output of 'pnpinfo' would be useful.

PNPBIOS gets extra info about devices including the motherboard resources.
It is only useful for PnP-aware device drivers, such as pcm/sbc etc.
Voxware is not a PnP-aware device driver so don't expect it to work on a
PnP card.

PNP OS = YES tells the motherboard to not bother configuring any hardware
that isn't needed to boot. This means things like sound cards and other
devices (pci and isa) are left in a totally unconfigured state.

This is because the bt878 has not been assigned any memory addresses. We
don't do PCIBIOS calls to reassign these yet, so if you use 'PNP OS = YES'
you are asking for trouble.

This is a quirk of the bt878 device and drivers. There are actually two
logical devices in the chip:
bktr0@pci0:10:0: class=0x040000 card=0x217d6606 chip=0x036e109e rev=0x02
none0@pci0:10:1: class=0x048000 card=0x217d6606 chip=0x0878109e rev=0x02
For whatever reason, the bktr driver is only interested in the first one
and leaves the second one unconfigured.

This is because you have 'device npx0 at isa? ...' - see GENERIC, it's
supposed to be 'at nexus?' or just 'device npx0'.

It's 'PNP OS = YES' that messes up the WinTV, not PNPBIOS.
Ahh, pcm/sbc do work.. Use that then, the Voxware code's days are numbered.

This is a different set of problems. make sure you are using an up-to-date
port and that you have rerun MAKEDEV to create the required devices in
/dev (in particular the xpt* and pass* devices.) Also, make sure you
have 'device pass0' in your kernel config.

Pretty much, yes. :-/
